  • Hi life,

    I made a test with your code, and I could reproduce your issue under Outlook 2013 and 2010. With restarting outlook, I could get 270 which is correct.

    Could you share us how you want deal with this value? Did you want to check whether there is someone replied this email or any other requirement about this value?

    Best Regards,
